Skeletons of the Sahara
University of Chicago paleontologist Paul Sereno, best known for unearthing new kinds of dinosaur bones around the world, found the largest known Stone Age human burial site on a sand dune in Niger. The oldest date from 8,000 to 10,000 years ago was during a time when the Sahara was green and lush. Filmmaker David Murdock follows Sereno and a team of archaeologists as they retrieve, date and identify the bones and the artifacts found with them.G
